Botanical Name

ROSA 'Radrazz'(KNOCK OUT®) PP11836

Plant Common Name

Knock Out® Rose, Shrub Rose

General Description

The Knock Out® roses are so easy and beautiful. These popular shrub roses are prized for their continuous bloom, hardiness, and disease resistance.

The original Knock Out® produces a profusion of mildly fragrant, semi-double, cherry-red roses all season. These appear above bright green foliage that is tinted with burgundy when it first emerges and then again in fall. Its flowers are followed by orange-red rosehips that are attractive to birds.

This low maintenance rose is very cold hardy. It prefers moist, well drained soil and full sun, but will accept light shade. Plant it in low growing hedges, mixed borders, or rose gardens.
